Figure 17 lists basic details of the six most popular OR gate ICs: Ways of cascading two-input 774hc132 gates to get up to five inputs.

Relatively few dedicated OR gate ICs are available. In this case, the unwanted inputs can be disabled by either tying them high directly in CMOS gates, or via a 1K resistor in TTL types or by simply shorting them directly to a used input.

Also note that OR gates can be directly 47hc132 to make a compound OR gate with any desired number of inputs. Learning Electronics Need to brush up on your electronics principles?

The 74LS10 and B see Figures 6 and 7 are triple three-input standard types; the 74LS20 and B see Figures 8 and 9 are dual four-input standard types; the 74LS30 and B see Figures 10 and 11 are eight-input standard types; and the 74HC is a input standard type.

Simple three kc diode OR gate.

The diode OR gate is reasonably fast, very cost-effective, and can readily be expanded to accept any number of inputs by simply adding one more diode to the circuit for each new input. The simplest way to make an OR gate is via a number of diodes and a single resistor, as shown for example in the three-input OR gate of Figure Just make sure the buffer has a fan-in of one in the former case, and a fan-in of two in the latter.

Note oc the fan-in of a TTL NOR gate is directly proportional to the number of inputs used — at a fan-in rate of one per 74hv132 — and that a TTL two-input OR gate can be made to act as a simple non-inverting buffer by either tying one input to ground 74h1c32 by tying both inputs together, as shown in Figure Part 4 Practical digital mixed gate and special-purpose logic gate ICs such as programmable logic, majority logic, and digital transmission gate types.

Figure 24for example, shows ways of cascading two-input elements to make OR gates with three, four, or five inputs, and Figure 25 shows a three-input OR element and a three-input diode OR gate cascaded to make a compound five-input OR gate. The output of an OR gate goes high when any of its inputs A or B, etc. Six popular OR gate ICs.
